You can buy any number of entries and then send them to other people to register their own details.
Check out using Speedy Checkout. The entries appear in your Race Space account marked Unregistered.
Log in with the email address you bought them with and go to My Entries in the main menu.
Select the SEND ENTRIES tab at the top.
Enter the first name and email address of the person you are sending the entry to, then select ASSIGN NOW.
They receive an email inviting them to complete their registration.
You can return to My Entries at any time to see which entries have been completed and which are still outstanding.
You do not have to send them. You can register the details yourself instead, if you have them.
